Ernest Martinez, 200 Hr NYT Yoga Research Team







Ernest, well…. what can I say, make your own notes…..

Ernest speaks…..”I have been enthusiastically teaching yoga for the last 7 years.  Fascinated with health and wellness, I have always been a self-proclaimed yogi– long before I even knew a “yogi” was more than a problematic cartoon bear.  I am thoroughly passionate about asana, but also passionate about living the Ashtanga philosophy and ideology (i.e. ahimsa,brahmacharya). Currently, I am “gently” working toward a degree in the medical field.  I am however, easily distracted by movement, so it may be that I end up working for the traveling circus.  Nevertheless, you can expect a well organized soothing experience in any of my classes.”
